Abstract
The present invention relates to a thermal inkjet print head, comprising a fluid feed channel for delivering fluid, fluid chambers arranged near the fluid feed channel, resistors for actuating the fluid in the chambers, arranged in a staggered pattern with respect to vertical printing lines. At least a part of the fluid feed channel opposite of a rear side of the print head extends substantially orthogonal to the chip surface, and the fluid channel having staggered edges follows the staggered pattern of the resistors so that a fluid path length between a resistor edge and a corresponding staggered edge is substantially similar for each resistor.
